Answer:
Antarctica
Explanation:
The Fisher glacier is located in Antarctica. It's located on the North sides of Mount Menzies and Mount Rubin and it is about 120 miles (200 km) long.
Most references separate this formation into two glaciers (Lambert and Fisher).
The Fisher glacier is a tributary of the Lambert glacier, which is listed as the largest glacier on the planet by the Guiness book of records, with boggling dimensions: 250 miles (400 km) long, 60 miles (100 km) wide and some 8,000 ft (2,500 m) deep!
